Teleglitch: Die More Edition

Seems I can't get past level 2 without getting this "Glitch" (get it? Uh, sorry...) that I get stuck (can't move, shoot, skip, etc). Sometimes it's later in level 3 or even in level 1. I tried verifying my game cache and everytime I do so, it says that 3 of my files failed to validate. Yes, everytime, well more like 2/3 of the time. I looked a bit, but there's no true fix yet. Thank you for any help, and sorry if my writting is bad, English isn't my main language c:

Edit* I think it work since I tried verifying game cache after reinstalling and it already said that all files were validated without any problem. Thanks m8 and thanks for the game to only be 100 + Mb c:
